ABSTRACT:
Kits adapted to allow subjective evaluation and communication of gemstones include a number of simulated gemstones which are arranged in an ordered set according to their respective hue, chroma and/or value characteristics. Each of the simulated gemstones includes a multifaceted gemstone body portion (which preferably closely resembles a brilliant cut diamond) and a handle portion radially extending from the body portion. The handle portion allows the multifaceted body portion to be manipulated in ambient light conditions so the color can be adequately observed. The simulated gemstones are formed of a molded plastics material which exhibits unique color hue, chroma and value characteristics. The hue, chroma and value characteristics may be varied within an ordered set of the simulated gemstones so as to achieve a close color match with natural gemstones. These ordered sets of simulated gemstones may thus be displayed in respective trays. Thus, the kits of this invention may be provided in multiple trays, with each tray being dedicated to a particular color set of the simulated gemstones.
